Seeing without eyes: the evolution of non-visual photoreceptors in vertebrates. Australia's underwater biodiversity is second to none with endemic species representing the earliest stages in vertebrate evolution, many of them relying heavily on vision for survival. Tracing the evolution of light detection and image formation will provide crucial information about the lifestyles of our vertebrate ancestors, the environmental selection pressures driving speciation and colour communication. Charact ....Seeing without eyes: the evolution of non-visual photoreceptors in vertebrates. Australia's underwater biodiversity is second to none with endemic species representing the earliest stages in vertebrate evolution, many of them relying heavily on vision for survival. Tracing the evolution of light detection and image formation will provide crucial information about the lifestyles of our vertebrate ancestors, the environmental selection pressures driving speciation and colour communication. Characterisation of optimal light environments and extra-ocular light detection will also help protect and manage endemic species in wild and captive environments. Read moreRead less
The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral ....Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral-algal symbioses. It will provide much-needed knowledge required to identify associations most appropriate for specific conditions, prioritise populations for conservation, and assess the feasibility of new approaches to managing and restoring coral reefs.

Buried treasure: bioactive plant seed proteins evolving inside hosts. This project aims to examine how evolution in plants shortcuts the creation of new proteins by burying one within another. Scientists now realise that new genes and proteins appear frequently. A recent discovery in plant seeds involves DNA sequence insertions in a gene that makes two proteins instead of one. This project will reveal a new family of buried seed proteins, determine the rules for burying them and search plants fo ....Buried treasure: bioactive plant seed proteins evolving inside hosts. This project aims to examine how evolution in plants shortcuts the creation of new proteins by burying one within another. Scientists now realise that new genes and proteins appear frequently. A recent discovery in plant seeds involves DNA sequence insertions in a gene that makes two proteins instead of one. This project will reveal a new family of buried seed proteins, determine the rules for burying them and search plants for new examples. The first examples from plants create strongly bioactive products so the ability to dig for similar plant events will reveal new and bioactive natural products with biomedical and biotechnology applications.Read moreRead less
How do sunflowers make protein drugs in their seeds? We recently discovered in sunflower the origin of a small protein ring that chemists have used for a decade to base designed drugs upon. This project aims to know how sunflowers make it so we may manipulate other plants to manufacture ring-based drugs.
A new and rapidly evolving class of plant peptides. The project will study a diverse class of drug-like mini-proteins that are thought to have emerged genetically over 12 million years ago. This project will explore why plants have kept making these mini-proteins for so long and whether it is the same reason the founding member of this mini-protein class is such a good drug.
